    Need help with sprocket ratios?

    Need help with sprocket ratios?
    I have a 12 volt dc motor that has a gear head on it and turns at 41 rpms . on the motor shaft i have put a 11 tooth gear and on the other shaft is a 60 tooth sprocket which gives me 5.5 rpm. I need 1 or 2 rpm at most what should I do?? can I put a 30 tooth sprocket on the motor will this give me the desired rpm or is the torque wrong.Should I get a gear head reducer and put it in line with the gears I have now. what is the best??
    Thanks for looking. L@@KING.
